One crucial detail was missing from Google's huge gaming announcement: Games!

Only a few games were teased during Google's Stadia reveal event this week, but the one big standout was "Doom Eternal."

It's the next major game in the classic "Doom" first-person-shooter series, and it's particularly notable here because it's a pretty demanding game in terms of hardware. It's a series known for being tremendously fast, and its fans demand pixel-perfect control.

In so many words, it's a great test case for what Google is promising: lag-free video games over modern broadband connection speeds.

Moreover, it's a clear sign of support from game publisher Bethesda Softworks — the same publisher behind the "Elder Scrolls" and "Fallout" franchises.

It's also clear that "Assassin's Creed Odyssey" publisher Ubisoft is on board — 2018's "Odyssey" has become a go-to demonstration of Google's streaming tech. The game was even used as the test for Google's Project Stream beta test in late 2018 (Project Stream was a public test of Stadia's streaming technology).

Two other notable publishers had games in the keynote: the "Final Fantasy" and "Tomb Raider" publisher Square Enix, and the "NBA 2K" publisher Take-Two Interactive.

These are all meaningful partners to have in the video game business. Ubisoft, Bethesda, Square Enix, and Take-Two are critically important multiplatform game publishers. But none of them are producing games exclusively for Stadia, and the company's first-party efforts are just getting started.

Going beyond working with various third-party game developers and publishers, Google is creating its own game-development division headed by the veteran video-game executive Jade Raymond.

The studio's goal is to "build experiences designed exclusively for Stadia as Google's own first-party game studio," Harrison said as he introduced Raymond.

It's not clear exactly how large the studio will be, or how many projects it will work on, but Raymond is known for her work on huge franchises, such as "Assassin's Creed."

What is clear is that Raymond is new to Google, and it often takes years to build major video games. It's entirely possible that Google's had a game or two in the works for some time now, but there were no big reveals of games from the newly-formed, first-party Stadia Games and Entertainment group at this week's event.

There were a few demos demonstrated on stage that Google created — but they were very much tech demos, like "Night Forest" seen above.

When Business Insider asked Google's director for games, Jack Buser, about what first-party games will be available when Stadia launches in 2019, he said: "We’re not talking too much about content just yet. But games are in my blood and I cannot wait to talk to you about it. We will definitely be able to talk more in 2019, so stay tuned. One thing I can say is that gamers should be quite impressed."

Google representatives said the company will share more details about Stadia — including a release date, a pricing model, and games — at some point this summer.

The service is scheduled to light up in the United States, Canada, and parts of Europe at some point in 2019.
